FOLDINGIBOARD FOR PAPER-HANGERS.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed October 20, 1909. Serial No. 523,596.

To all whom it may concern:

Be it known that I, JOHN G. BRECKEN- RIDGE, a citizen of the UnitedStates, residing at Springfield, in the county of Clark and State ofOhio, have invented certain new and useful Improvements in FoldingBoards for Paper-Hangers, of which the following is a specification.

My invention relates to paste boards for use by paper-hangers andadapted to analogous uses.

My improvement especially relates to the arrangement of hinged pasteboards whereby a long board may be transported readily from place toplace and when opened out will be capable of satisfactory use incombination with pedestals supporting the boards at its ends as a table.

For many years it has been desirable to have paste boards that could bereadily transported by street cars or other agencies and as these boardsare necessarily long it has been desirable to hinge them in some way sothat they could be closed during transportation and opened up at anytime for use, a requirement being that the hinging thereof should not inany way weaken the structure for its particular use.

Referring to the drawings: Figure 1 is a side elevat on of the two pasteboards set up for use. Figs. 2 and 5 are detail views of the hingedconstruction. Fig. 3 is a detail view of part of the paste board. Fig. 4is a longitudinal sectional view showing the hinged paste boards in openposition.

Like letters of reference indicate like parts throughout the severalviews.

Referring to Fig. 1 the pedestals are indicated by a and a and it isapparent that in this character of device the pedestals are located atthe free ends of the paste board so that the center of the board isunsupported. It is very important that the center of the board thereforebe reinforced from collapsing and my improvement specifically relates tothe device which not only reinforces the center of the board withoutinterfering with its use as a paste board or table but permits theboards to be closed in compact form ready for transportation. There ispreferably formed on each flap a a comprising the paste board near oneend thereof a small groove extending transversely to the board asindicated in Figs. 2 and 5. There are preferably employed two pairs ofhinges b and b for each flap. These hinges are turned up at their endsthereby forming a projecting flange 6 and this projecting flange extendswithin the groove formed in the bottom of the boards. It is alsodesirable to so space the hinges and so form the groove as to minimizethe danger of weakening the paste board while at the same time theupturned flanges of the hinges in combination with the edges of theboards reinforce the same so as to form a very strong paste boardespecially at its center. It is apparent that if any great strain isexerted downwardly at the center of the board the strain will be borneby the hinges and because the flange b engages in the grooves the innerends 0 and c of the flaps a will cooperate with said hinges to resistany such strains. The pintle for the hinges comprises a rod 0 whichextends through the hinges in any usual and ordinary manner such thatthe flaps a and a can be readily closed as heretofore described.

Having thus described my invention, I

claim As an article of manufacture, a collapsible paste-board comprisinga plurality of pairs of flaps capable of being supported entirely by theouter ends of the flaps a plurality of pairs of hinges secured to theinner ends of the flaps. projecting flanges extending transversely fromeach of the several parts of each pair of said hinges and transversegrooves formed in the under sides of each of the flaps and a pintlecommon to the pairs of hinges of a pair of flaps and near the inneredges of the flaps whereby the flanges will be held against movement bythe grooves when the paste-board is supported at its outer ends,substantially as specified.

In testimony whereof, I have hereunto set my hand this 14th day ofOctober 1909.

JOHN G. BRECKENRIDGE.
